charge pump current phase noise
For a conventional PLL, integer-N and 2nd loop filter.
If I reduce the charge pump current and modify the loop filter to maintain
the same loop bandwidth. All other components are the same. The phase noise
will be improved or degraded? Why?
Let's discuss this in two aspects, in band and out band phase noise.
